These are the key databases that index the nanotechnology literature--journal articles and (depending on the database) conference papers and patents. The articles are either full text within the database or easily accessible through a link in the record, and if not, you should also see a button to get a link to the article via UC Library Search, or to request the article through interlibrary loan. You can also use UC Library Search to find articles (limit results to peer-reviewed journals).
